About Us

As an ISO9001-certified manufacturer serving 2,000+ industrial clients, Yuanzhi introduces the D650 mechanical advanced leak tester for demanding pipeline and component testing. Differential pressure technology delivers 0.1Pa/s resolution with a test range extending to 1600kPa, covering both vacuum and high-pressure applications on one platform. Sixty-four parameter channels and 16 I/O ports enable fast changeover and PLC integration, while 50,000-record storage supports full quality traceability.

For components with large internal volumes where pressure decay is too slow, Yuanzhi delivers the F650 flow-type leak detector with a measurement range from 5mL/min to 100L/min. A 2MPa-rated differential sensor and 0.01kPa resolution provide stable flow readings across test pressures from -100kPa to 1000kPa. The 5.6-inch touchscreen manages 64 parameter profiles and 50,000 stored records, with Ethernet and RS485 for line integration. ISO9001-certified manufacturer with 10,000+ active installations.

The P670 series consists of direct pressure leak testers designed for stable and reliable airtightness testing under different test pressure requirements.

• Multiple test pressure options and measurement ranges are available.
• Equipped with Ethernet, RS232, and RS485 communication interfaces.
• Supports connections to compatible barcode scanners and label printers.
• Stored parameter profiles can be named in Chinese or English.
• Powered by a DC24V low-voltage power supply.
• Mechanical pressure adjustment through a manual control knob.

Yuanzhi, an ISO9001-certified manufacturer, presents the P650 electronic touchscreen leak tester designed for precision electronics assembly environments. Electronic pressure regulation eliminates manual knob drift and delivers repeatable 0.001kPa readings across every shift. The 5.6-inch industrial resistive touchscreen supports 64 parameter profiles and 50,000-record storage, with PLC-ready I/O for seamless line integration. Deployed by 2,000+ industrial clients in 10,000+ active installations.​

As an ISO9001-certified manufacturer, Yuanzhi delivers the P650 direct-pressure leak tester engineered for high-volume automotive production lines. Its 0.001kPa pressure resolution catches micro-leaks that competing instruments miss, while 64 parameter channels accelerate product changeovers. Each unit stores 50,000 test records and exports traceable Excel reports via Ethernet or RS485. Trusted by over 2,000 industrial clients across 10,000+ active installations worldwide.
